Separate the width adjustment controls in the timeline for "Mode" and "Track Matte" columns

I would like to recommend separating the width of the timeline columns for "Mode" and "Track Matte" which are currently locked together. These should have separate width adjustment controls so that they can each be adjusted individually.
When I need to see the a long filename in the Track Matte column it doesn't mean I need the Mode column to equal it's width. Why would it?

Having them connected means that my timeline becomes unnecessarily covered/truncated.

This isn't a critical issue, just a confusing one and one that it seems like it shouldn't be difficult to address.

Thanks for considering separating these column width controls in an upcoming release!
